CCS/CC1312R: File Loader: Memory write failed.

Part Number: CC1312R

Tool/software: Code Composer Studio

Hello,

I am working on CC1312 custom boards. They work fine, except for one of them, which exhibits the following problem:

If the device has already been programmed, I receive this error when I try programming it again:

Cortex_M4_0: GEL Output: Memory Map Initialization Complete.
Cortex_M4_0: GEL Output: Board Reset Complete.
Cortex_M4_0: Target timed out! (Block 0)
Cortex_M4_0:   Status 0xFFFFFFFF: Target flashloader has not returned any status. Unknown error!
Cortex_M4_0:   Command=20 -- addr=0x00002000 -- length=0x00002000
Cortex_M4_0: File Loader: Memory write failed: Timed out waiting for target flashloader to execute command.

I have two choices then to "fix":

1. Power cycle the device;

2. Erase flash memory

I use a LaunchPad with XDS110 two-wire JTAG to program, voltages look good. I have also tried slowing down the JTAG clock, to no avail.

Any pointers where to look and what to try are appreciated.
